I contacted my Munich friends, and got this info back:
Sandra Patricia Ghella-Schroeder is currently a Chief Design Engineer at BMW. Gali is her nickname.
So, that explains the fact Hussein was seeing her constantly in the Design department area.
Before that she was fully responsible for further development & production supervision of E60 5er, E63 6er & E65 7er. Meaning: she was a project manager responsible for facelifts of BMW large cars (5er, 6er, 7er).
Even before she was a development chief for N62 V8 engines. And even before she was an engine development engineer.

Top design engineer position is indeed very high in the Development department hierarchy.
Hat down!
Beside Verena C. Kloos (President of BMW DesignWorksUSA) I think this lady is the only one so high in BMW hierarchy. And even in top engineering position.
Guys, your BMWs are being developed by a woman.

I met her in Frankfurt years ago. She is a complete engine freak. At least then she was. If you think Scott or I are diehard BMW fanatics you should meet her.

She's 100 times worse.
PS: Btw, Google says she was born in Venezuela. Having Italian & Spanish roots.
